How do I get into playing chess and solving rubicks cubes?

I mean aside from the fact that it makes you very hot 😼, I believe that it enhances your problem solving skills too? Because all the "baniyas" I know have skillfully mastered both of these lmao

I'm completely out of the depth when it comes to these two but I think it's time I start getting into them (and yes I'm def not finding a hobby to give a boost to my dopamine receptors that are fried beyond repair except for doom scrolling)
